 Subject: [mdoc] wrong interpretation of '".Bl ... -width "long string"' 

  Example (with a modified file '~/.manpath' and environmental variables
"MAN..."):

N.B.  Stripped 'doc.tmac' used.

"man erb3.1 > /dev/null" shows

troff: backtrace: '/home/bg/git/groff/build/s-tmac/doc.tmac':1803: macro
'doc-do-Bl-args'
troff: backtrace: '/home/bg/git/groff/build/s-tmac/doc.tmac':1715: macro 'Bl'
troff: backtrace: file '<standard input>':34
troff:<standard input>:34: warning: integer value saturated
troff: backtrace: '/home/bg/git/groff/build/s-tmac/doc.tmac':1804: macro
'doc-do-Bl-args'
troff: backtrace: '/home/bg/git/groff/build/s-tmac/doc.tmac':1715: macro 'Bl'
troff: backtrace: file '<standard input>':34
troff:<standard input>:34: warning: integer value saturated
troff: backtrace: '/home/bg/git/groff/build/s-tmac/doc.tmac':1811: macro
'doc-do-Bl-args'
troff: backtrace: '/home/bg/git/groff/build/s-tmac/doc.tmac':1715: macro 'Bl'
troff: backtrace: file '<standard input>':34
troff:<standard input>:34: warning: integer value saturated
....

  Line 34 is:

.Bl -tag -width "1234567890123" -compact

-.-

  File is in the Debian package "ruby3.1" (and ruby3.3).

  Changes to '~/.manpath' are:

DEFINE  troff test-groff -b -ww -s -mandoc -rCHECKSTYLE=5 -dpaper=a4 -K utf8
-fU-T
DEFINE  nroff test-nroff -b -ww -s -mandoc -rCHECKSTYLE=0

  Environmental variables:

MANOPT=-E latin1
MANROFFOPT=-rF=0 -dAD=l -rHY=0 -dMF=R -rLL=80m -rLT=80m
MAN_KEEP_STDERR=yes
 
N.B.  What integer's value is saturated? (the name of the integer variable?)
