Subject: mdocml: Minimal COMPATIBILITY cleanup: * Mention that the list is
Date: Sun, 22 Jun 2014 13:07:06 -0400 (EDT) [thread overview]
Message-ID: <201406221707.s5MH76fl005715@krisdoz.my.domain> (raw)
Log Message:
-----------
Minimal COMPATIBILITY cleanup:
* Mention that the list is incomplete.
* I implemented %C for groff -current, and it was accepted.
* Font family is \F, not \f.
* Escapes and scaling widths are documented in roff(7), not here.
* Quoting quotes by doubling them is now supported.
