troff: ../doc/automake.mom:710: warning: empty parentheses
Line 2103 corresponds to line 3358 in "mom/om.tac".
Code:
. ie '\\$1'' \{\
. br
. in \\n[#L_INDENT]u
. ta \\n[.l]u-\\n[#L_INDENT]u
. \}
. el \{\
. br
. nr #L_INDENT +(\\$1)
. in \\n[#L_INDENT]u
. ta \\n[.l]u-\\n[#L_INDENT]u
. \}
. if \\n[#IN_ITEM] .nr #IN_ITEM_L_INDENT +(\\$1)
The last line needs to be moved into both branches,
to the first with the value "+0" and to the second unchanged.
