[pacman-dev] [PATCH] repo-remove: Fix infinite loop when given a pkgname ending in '*'

[Rafael Ascensão]

While this is most likely the result of user error, as repo-remove
doesn't accept globs, using 'package*' as the pkgname will result in an
endless loop of the following message being printed:

  -> Removing existing entry 'package**'...

This happens because find_pkgentry() fails to account the case where
globbing fails and the expression is taken literally. Fix that by
checking the existence of the file before doing anything else.
