617d46633e top: redesign Uniq_nlstab/show_special (nls quirks)
Until this patch, top had used some strings with
special escape sequences to produce colors, normal
text, bold text, etc.  They took the following form,
explained by an excerpt from program comments:
  ...
  Our special formatting consists of:
     "some text <_delimiter_> some more text <_delimiter_>...\n"
  Where <_delimiter_> is a single byte in the range of:
     \001 through \010  (in decimalizee, 1 - 8)
  and is used to select an 'attribute' from a capabilities table
  which is then applied to the *preceding* substring.
  ...

Unfortunately, these nonprinting values revealed
insurmountable inconsistencies in both the front-end
and back-end translation tools.

The xgettext (extraction) program would take those
special escapes, convert them and then output raw
binary values.  Thus the .pot file would contain
lots of unprintable stuff making it unreadable.

If the following was added to po/Makevars, most of
those special escapes would be preserved in their
escape notation:
  XGETTEXT_OPTIONS = ... --escape
But two escapes were converted from octal notation
and there was no way to prevent it:
  \007  -->  \a
  \010  -->  \b

After a pass through the msginit program, most of
the escapes were reconverted to raw binary values
making translation impossible.  There was no
"--escape" option for the back-end programs like
there was for xgettext.

But the real killer was the escape \004, also used
in some of top's special strings.  This value would
be silently accepted by xgettext, only to produce
the following fatal error in back-end programs like
msginit, msgfmt and msgen:
  .pot:2647: context separator <EOT> within string

To quote from one of the references below:
  "Would you create a suite of tools that silently
   allow what is destined to become a fatal error
   to pass unnoticed?"

So the bottom line was: top's special strings, in
use for the past nine years, had to be redesigned.

3f7468082a top: finalized top nls support (or so he thought)
summary of changes:
. adopted relative paths to 'include' and 'proc'
  dirs so that stand alone compiles are made
  easier and no one need guess their locations

. corrected several names for enums and macro
  usage reflecting fmt vs. txt

. expanded all octal escape sequences to a full
  3 digits since one already required 3 digits

. finalized translator hints (for now)

programming note:
  as an aside, by not including an argument for
  the gettext --add-comments, any preceeding c
  style comment will be propagated to the .pot
  file, if the gettext macro isn't empty.

  /* Need Not Say 'TRANSLATORS' ...
  snprintf(buf, sizeof(buf), "%s", _(   // unseen
  /* Translator Hint: ...
  snprintf(buf, sizeof(buf), "%s", _("" // seen

05f5deb97c top: with lib xalloc changes, restored prior memory logic
With the privatization of the library xalloc functions,
this patch restores top's previous internal memory logic.

This puts us back on a 3.3.1 (and earlier) footing wherein
memory allocation errors carry these implications:
  . if top detected, the terminal will be restored
    prior to an abnormal exit and message
  . if library detected, the terminal will become
    corrupted following the message

To my knowledge, neither type of memory error has ever occurred
during the nine years since top was rewritten.  So the issue of
restoring the termios structure is probably moot.

a10282422b sysctl: enable pattern matching with path
Pattern matching support in `sysctl: implement --pattern option'
commit did not work when variable path was defined, for example

$ sysctl net.ipv4 -r arp.ignore

gave no output. Reason being was tht the pattern was matched agains
the specified argument and not the output variable list.
