these actions are kind of "meta" actions, combining getpkgdepname and
getpkgname (and the respective version actions) so that a list of mixed
pkgvers and package patterns can be interpreted. This uses the internal
format check of `xbps_pkgpattern_{name,version}()` to allow for a
fallback to `xbps_pkg_{name,version}()` for exact versions, then falls
back to displaying an error message if that also fails.
- use `.Os` to show "Void Linux" in the footer
- use `Aq Mt` to display email addresses
- use `.Lk` for the bug link
- remove unnecessary use of `.Nm <name>` when already defined
- add xbps-alternatives(1) to SEE ALSO where missing
- bump date
Instead of just cryptically exiting 0 when opening a non-existant
repodata or stagedata, with the only message existing in the debug
output, show an error to the user on stderr.
mentioned in #519
If repodir is given as a relative path, it will not work because it will
try to open the dir relative to itself because it already chdir()ed into
repodir. This fixes xbps-rindex -r when relative paths are specified.
