Index: src/tbl/t7.c Fix
Description:
The "tbl" command may output a troff ".ne" directive that's larger
than the size of the table being produced.
Repeat-By:
Create a file with these lines (eliminating the leading indent):
echo '
.TS
box ;
l l .
x
_ _
x
.TE
' | tbl | fgrep .ne
(Note that the character between the two underscores above is a tab.)
Now run the file through "sh" and note the result:
.ne 3v+0p
Next edit the above file, changing the line with the two underscores
to a line with just a single underscore on it. Run the file through
"sh" again and note the result:
.ne 2v+2p
Even though the two versions of the file produce identical-looking
output when "typeset," the size that tbl claims is needed is different.
Fix:
Here's the fix to the 4.1bsd version of "src/tbl/t7.c". As usual,
the trade secret status of the code involved precludes a clearer
posting. The fix is an addition to the function "need",
conditioned on "OLDVERSION":
...
if (instead[i]!=0)
continue;
else
#ifndef OLDVERSION
if (allh(i))
horlin++;
else
#endif
texlin++;
...
