man*/: srcfix

[Clean up in preparation for "MR sed".]

Drop spurious, nilpotent uses of *roff `\c` escape sequence.

Quoting groff_man_style(7):

    \c  End a text line without inserting space or attempting a break.
        Normally, if filling is enabled, the end of a text line is
        treated like a space; an output line _may_ be broken there (if
        not, an adjustable space is inserted); if filling is disabled,
        the line _will_ be broken there, as in .EX/.EE examples.  The
        next line is interpreted as usual and can include a macro call
        (contrast with \newline).  \c is useful when three font styles
        are needed in a single word, as in a command synopsis.
