Mon 28 Apr 2008 05:54:07 PM UTC, comment #2: Sure, I think it's fixed enough. Though keeping warnings at output time seems a bit too late, when the original roff processing could warn when a document has an unreasonably small minimum wrap.	Bryce Nesbitt <brycenesbitt>
Mon 28 Apr 2008 08:45:45 AM UTC, comment #1: With man-db 2.5.0 or newer (I recommend 2.5.1, as there was a mistake in this change in 2.5.0), those messages won't disrupt normal pager output any more. Is this enough for you to consider this bug fixed? From docs/NEWS: o man now discards stderr from formatting subprocesses when outputting to a pager, to avoid visual corruption from any error messages. You can suppress the warnings entirely (in 2.5.1 or newer) by setting MANROFFOPT=-Wbreak. I'm unsure about whether this should be the default; they do represent real infelicities in groff's output and it seems somewhat reasonable for lint-type tools to be able to warn about them (at more comfortable page widths) in case there are ways for the page to be rewritten to avoid such problems.

Mon 28 Apr 2008 01:20:58 AM UTC, original submission: When a line can't wrap, I get a series of ugly warning messages that disrupt use of man. I encountered this with reasonably wide terminal, but to see it just set something narrow like: shell> MANWIDTH=20 man man /usr/share/man/man1/man.1.gz:714: warning [p 34, 4.3i]: cannot adjust line /usr/share/man/man1/man.1.gz:714: warning [p 34, 4.5i]: can't break line /usr/share/man/man1/man.1.gz:716: warning [p 34, 4.8i, div `an-div', 0.0i]: cannot adjust line ... The warnings don't help much, could they be suppressed?	Bryce Nesbitt <brycenesbitt>
