bug#21496: 25.0.50; guile-file compilation-error regexp is too wide

Indeed, thank you.  Installed.
We should file a bug report with the Guile guys: they should better
follow the GNU Coding Standard in their error messages (i.e. use
<file>:<line> rather than having the file name on some earlier line).

Great.  For now I installed it as a "tiny change", but indeed if you
want to provide further changes, it's better to sign the paperwork.

You can put me on the Cc, but as long as things are working normally,
it's not needed.
