5bef6781fa vi: fix range selection by forward character motion
Selection of ranges for change/delete/yank by forward character
motion commands (SPACE or 'l') was incorrect.  The range was
always one character whereas vi allows the size of the range to
be specified.

Fix this by executing the motion command the required number of times.
There is a complication when the range is at the end of a line.  We need
to distinguish between a range which excludes the last character and
one which includes it.  This requires comparing the actual range with
that expected from the command count.  (With the additional quirk that
a command count of zero is equivalent to a command count of one.)

bcf91d2760 libbb: code shrink and speed up index_in_strings()
Rewrite index_in_strings() to replace calls to strcmp()/strlen().
With this change searching for valid names in the applet_names
array (for example) is 40% faster.

The code has to assume the strings aren't sorted, so will always scan
the entire array when presented with an invalid name.

59120c3303 libbb: code shrink and speed up find_applet_by_name()
find_applet_by_name() determines the appropriate range of applet
indices to check for the given name and performs a linear search in
applet_names[].

Revise the code so the index of the upper bound of the range, 'max',
isn't calculated.  Instead check the value of the first non-matching
character to see if we've reached the end of the range.

This new code speeds up the time to find a valid applet name by 6%
and halves the time to detect that a given name is invalid.  The
average time to detect an invalid name is now the same as for a valid
one.

e8fe9f9635 awk: allow printf('%c') to output NUL, closes 13486
Treat the output of printf as binary rather than a null-terminated
string so that NUL characters can be output.

This is considered to be a GNU extension, though it's also available
in mawk and FreeBSD's awk.
