Can reproduce if I copy the emitted tag literally into
debian/source/lintian-overrides although it should work as override:
prefer-uscan-symlink filenamemangle
s/.*muted..([\d\.]+)..span./@PACKAGE@-$1\.tar\.gz/ [debian/watch:19]
With a bit of debug code (I added "die $re if $glob =~ /file/;" into
lib/Lintian/Utils.pm around line 404) it shows me that the override
was converted into this regular expression:
filenamemangle
s\/\..*muted\.\.\(\[\\d\.\]\+\)\.\.span\.\/\@PACKAGE\@\-\$1\.tar\.gz\/
\[debian\/watch\:19\]
Looks as expected to me on a first glance, but actually all occurences
of "\." are not properly converted to "\\\." while "\d" is properly
converted to "\\d". I can also reproduce with this minimal reproducer:
$ perl -MRegexp::Wildcards -E 'my $rw = Regexp::Wildcards->new(type =>
"jokers"); say $rw->convert(q{\.\d})'
\.\\d
So this actually seems to be a bug in libregexp-wildcards-perl. Hence
reassigning.

Sure it is, just replace all the ugly stuff with an asterisk or omit
all parameters after the tag name. All these overrides work for me:
prefer-uscan-symlink filenamemangle s/*/ [debian/watch:19]
prefer-uscan-symlink filenamemangle * [debian/watch:19]
prefer-uscan-symlink filenamemangle *
prefer-uscan-symlink

Yes and no. It interprets only "*" and "?" and these have the same
meaning as with shell wildcards. It's actually the "jokers" mode of
the Perl module Regexp::Wildcards.
