Use a single-font-style macro (".B", ".I") for a single argument.
Remove a superfluous ".RE" in "malloc.3".
Remove unneeded quotation marks (").
Separate "()" from the name of a function in file "nl_langinfo.3".
The output from "nroff" and "groff" is unchanged, except for the style
of the parentheses of a function name in "nl_langinfo.3".
