This change might help to c+p a fingerprint from an HTML page without
being enclosed in a "pre" tag.
* common/userids.c (classify_user_id): Skip a second blank in the
middle of a fingerprint.
Since 2009-12-08 gpg was not able to find email addresses indicated
by a leading '<'. This happened when I merged the user id
classification code of gpgsm and gpg.
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
