[notmuch] [PATCH] fix notmuch-new bug when database path ends with a trailing /

Subject: [notmuch] [PATCH] fix notmuch-new bug when database path ends with a trailing /

I configured my database.path with a trailing /, and after running notmuch
new every notmuch search would fail with error messages like this:

  Error opening /inbox/cur/1258565257.000211.mbox:2,S: No such file or directory

The actual bug was in the filename normalization for storage in the
database.  The database.path was removed from the full filename, but if
the database.path from the config file contained a trailing /, the
relative file name would retain an extra leading /... which made it look
like an absolute path after it was read out from the DB.
