8a38cd5eb4 Split help lines to help translators
To assist translators, the help lines are split so that each translation
chunk has one option. This gives bonus of if we add or change an option,
only that option remains untranslated rather than the entire help block.

764e27a4dd Increase watch interval.
watch would only use an interval of up to 4294 seconds and silently
change to this limit. The 4294 seconds is 2^32/10^6 or how many
microseconds fit into unsigned int.

This change increases the limit to 2^32 seconds which is
approximately 136 years. This should be ok for now. Anything above
the old limit now uses sleep() instead of usleep() which only uses
integers (so 9999.123 seconds will be 9999 seconds)

This bug was first reported in 2006 and included a patch by
Stephen Kratzer. The patch was updated to fit the current source.

042776e04c configure: check for program_invocation_name
For portabiliy, check for program_invocation_name during configure and
define HAVE_PROGRAM_INVOCATION_NAME accordingly. Use of this symbol is
now enclosed with the appropriate #ifdef block.

The symbol program_invocation_name is only used for error message
handling using error(), so it's safe to omit this if it is not
available.

ddfc402886 Don't check if output changed on first screen.
When invoked with the --chgexit/-g options wait until we have at
least one screen of output before checking if the output changed.
Otherwise, we're comparing the initial screen of output to all
spaces, which usually isn't what we want.

f5a3afdcae watch: exit cleanly when falling through main loop.
Revert commit ffe5e0b08e.  Restores
clean exit when falling through main loop.

Previously, watch only exited when there was an error or when
interrupted by the user.  Commit 81f64657ba
added another exit condition when the watched command's output
changes, causing execution to fall out of the main loop.

With this change, watch correctly restores the terminal and returns
an exit code indicating success when invoked with the --chgexit/-g
options.

81f64657ba watch: exit when command output changes.
Add new flags to watch (-g/--chgexit) so that it exits when the
output changes.  This is useful in builds and shell scripts, for
example when deploying webapps to block the remainder of the
deployment steps until after the webapp starts.

e.g. watch --chgexit curl http://foo/bar

f776e59123 fixed e and x options in watch
The -e option would print a confusing error message. This is because
most error messages in watch are one word.  This fix makes a more
sensible message about what went wrong.

The -x option exited before the endwin() function was called, so if the
child process died the terminal was left in a funky state. endwin is now
called just before the exit(8) for the -x option.

fb11e1fe0a Changed the err and warns to macros
err and warn are BSD format but they are not recommended by library
developers.  However their consiseness is useful!

The solution is to use some macros that create xerr etc which then
just map to the error() function.  The next problem is error() uses
program_invocation_name so we set this to program_invovation_short_name

This is a global set but seems to be the convention (or at least errors
are on the short name only) used everywhere else.
