[PATCH 1/2] checkpatch: tolerate long lines w/o spaces

[Jim Cromie]

checkpatch complains about long lines (>75 chars), but allows a few
exceptions:

 file delta changes
 filename then :
 A Fixes:, link or signature tag line

Add another exception, to allow a long "word" without whitespace.  The
regex allows spaces in 1st 10 chars, so it allows the following [1],
which current checkpatch carps about.
