Subject: 24.5; Inconsistent text reflow in man pages depending on window
 configuration
Date: Thu, 31 Mar 2016 15:15:15 +0200

Before the man process is started, "Man-start-calling" calculates the "COLUMNS"
envvar using "window-width" before splitting windows. The window split happens
later once the process finishes, and the buffer is shown through
"Man-notify-when-ready".

Assuming the buffer is going to be shown on a vertical split, the text will go
beyond the window limits if there was no other window in the frame (or if a new
window is used), or will be reflowed with the proper width if an existing window
is reused.

Manually calling "Man-update-manpage" fixes it, but it's annoying. Simply adding
a call to "Man-update-manpage" in "Man-notify-when-ready" would fix it
("(with-current-buffer man-buffer (Man-update-manpage))" in the "friendly" case
for me).

As a bonus, this fix also reflows the text when an existing buffer is reused.


Thanks,
  Lluis
