[PATCH v3] man*/: srcfix

["G. Branden Robinson" <g.branden.robinson@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 5790 bytes --]

Clean up in preparation for "MR sed".

Format only one man page cross reference per input line.

Also, groff 1.23.0's (and Plan 9 from User Space's) `MR` is not a font
style alternation macro; there is no "reversed" form as with `BR` and
`RB`.  So when a man page cross reference must be immediately preceded
by punctuation, put that punctuation on the previous text line and use
the `\c` escape sequence to connect them.

v2: Fix goof that boldfaced some opening parentheses in credentials(7).
