Bug#750563: uscan regressed recently, adding all groups to the version number match

[Matthias Klose]

Package: devscripts
Version: 2.14.4
Severity: important

libffi currently reports as version number 3.1.gz using

  ftp://sourceware.org/pub/libffi/libffi-(.*)\.tar.(bz2|gz|xz)

looks like every () group is added to the version number, this did work before.
 Didn't look how many watch files are affected by this change.  Changing the
pattern to

  ftp://sourceware.org/pub/libffi/libffi-(.*)\.tar.*

works around it.
