In shuffling around the updating of +REQUIRED_BY I forgot to delete
empty grep_deps files. [1]
While I'm looking at unlink'ing files, bring some sanity to the various
places that it's done which haven't been reviewed in a while:
* Fix the pm_unlink* functions to use the builtin test
* Only/always call the function when we're not sure if the file exists
* Just use /bin/unlink when we're sure it does
* In parent_exit the glob pattern in the for loop will return 'pattern-*'
if there are no matches, so test for that specifically rather than
returning to the conditional version.
The mere presence of IS_INTERACTIVE in the Makefile is not enough, the
condition needs to be verified in case it is conditional [2]
We want to make sure that $TMPDIR exists before trying to use it. The
cheapest way to do this is to just call mkdir -p. Move the umask call
before this to be safe.
Split the test for the existence of /usr/X11R6 and whether or not it's
a link for one more micro-optimization.
