merge: make error message consistent with other commands

If a merge is attempted when another merge is already ongoing, we give
the message "outstanding uncommitted merges". Many other commands
(such as backout, rebase, histedit) give the same message in singular
form. Since the singular form also seems to make more sense, let's use
that for 'hg merge' as well.

 Test "hg status" with combination of 'file pattern' and 'directory
 pattern' for largefiles:
 
   $ hg status sub2/large6 sub2

 Config settings (pattern **.dat, minsize 2 MB) are respected.

   $ hg add
   adding reallylarge as a largefile
   adding test.dat as a largefile
 
 Test that minsize and --lfsize handle float values;
 also tests that --lfsize overrides largefiles.minsize.

   adding medium
   $ hg forget medium
   $ hg --config largefiles.minsize=.25 add --lfsize=.125

   $ hg --config largefiles.minsize=.25 add --lfsize=.125

 More rebase testing, but also test that the largefiles are downloaded from
 'default-push' when no source is specified (issue3584). (The largefile from the
 pulled revision is however not downloaded but found in the local cache.)
 Largefiles are fetched for the new pulled revision, not for existing revisions,
 rebased or not.
