Commit d94c811 changed `sort -u` to `uniq -u`; these are not equivalent.
`uniq -u` suppresses all duplicate lines, but `sort -u` removes all but
one. In the case of there being no command-line args, PWD is taken as
the package, and if that package is in a repo already in KISS_PATH, the
repo will be in KISS_PATH twice. This will cause the `kiss search`
command to give two entries for PWD, and `uniq -u` removes both.
Revert to `sort -u` to keep one of those entries.
If the package in PWD is not installed, there will be not entries left;
if it is installed, kiss-maintainer will try to get the history from
/var/db/kiss/installed/pkg, which is not a git repo.
Example of the incorrect behaviour:
KISS_PATH=/home/me/repo/core
PWD=/home/me/repo/core/musl
$ sh -x /usr/bin/kiss-maintainer
+ '[' ]
+ export 'KISS_PATH=/home/me/repo/core::/home/me/repo/core'
+ set -- musl
+ kiss search musl
+ uniq -u
+ read -r repo
+ read -r repo
+ cd /var/db/kiss/installed/musl
+ git log -1 version
+ m=
+ :
+ m=
+ m=
+ '[' ]
+ continue
+ read -r repo
(no output)
Seeing as how these utilities are now better integrated,
more effort should go into the overall interface between
what should be the "benchmark" or example kiss scripts.
kiss' help output will now include all executables found in $PATH
which begin with kiss-*. A comment string is optionally usable via
setting the second line of the script to a string.
Example:
...
This also means that 'kiss <script name>' is also possible now.
If I have a script in my $PATH called kiss-depends, I can now use
it via kiss with 'kiss depends'.
