Hi all
I am running mc-4.6.1 compiled from the unstable Debian source package
under Debian Sarge.
I have occasionally come across problems with displaying files using F3.
Either I get repeated error messages such as:
warning [p 1, 9.8i]: cannot adjust line
displayed on the screen before the file is displayed, or else MC hangs
completely.
I investigated further when one particular RFC-822 message file always
caused MC to hang. The command that was being run by MC to display the
file was:
nroff -c -Tlatin1 -mandoc msg_remainder.1576tS.1
A check on Google indicates that the above warning "cannot adjust line"
can be fixed by calling groff with the -Ww parameter to eliminate warning
messages. I therefore edited the following line in the /usr/bin/nroff
script (which is generally used for displaying man pages):
PATH=$GROFF_BIN_PATH:$PATH groff -mtty-char $T $opts ${1+"$@"}
to
PATH=$GROFF_BIN_PATH:$PATH groff -Ww -mtty-char $T $opts ${1+"$@"}
and this appears to have fixed the problem. Ironically the above section
is preceded by the following comments in the script:
# This shell script is intended for use with man, so warnings are
# probably not wanted. Also load nroff-style character definitions.
In addition, the man page for nroff states explicitly:
NOTES
This shell script is basically intended for use with man(1), so
warnings are suppressed.
(but they are not)
I see that Red Hat 7.1 has the following equivalent line in their nroff
script:
PATH=$GROFF_BIN_PATH:$PATH groff $safer -Wall -mtty-char $T $opts
${1+"$@"}
which inhibits all except a handful of warning messages.
Is this not a problem that should be fixed in the Debian distributions?
Perhaps the testing/unstable versions have changed it already.
