Subject: [PATCH] tbl/table.cpp: avoid creating a trailing space when the last
 column is centered

  Directory: src/preproc/

  The padding character is "^C" in ".fc ^B^C" ('^'
means a control character)

  Example:

.TS
c .
centered
.TE

/usr/bin/tbl <file> :

[...]
.fc ^B^C
[...]
.nr 3cl0 0*\n[3sep]
[...]
\&\h'|\n[3cl0]u'^B^Ccentered^C^B

  The last padding character is interpreted as a space character(?),
but is removed in "env.cpp" (strip trailing spaces) without reporting
it.

  The fix is to remove the last '^C'.
