[PATCH v3 10/13] intro.3: srcfix

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

[-- Attachment #1: Type: text/plain, Size: 3964 bytes --]

* Break input lines at phrase boundaries more often.
* Break input lines after commas.
* Set multi-word parentheticals on their own input lines.
* Protect man page cross reference from hyphenation.  (This will not be
  necessary upon migration to groff 1.23's `MR` macro.)
