Here's what I'm committing. 2007-12-25 Paul Eggert <[EMAIL PROTECTED]> Bruno Haible <[EMAIL PROTECTED]>
Avoid using the syntax symbol() in formatted documentation. * MODULES.html.sh (func_module): When replacing symbol() with a hyperlink, remove the parentheses. Show an error if some remain. Recognize and render the '...' syntax. * doc/alloca-opt.texi: Remove parentheses from symbol reference. Rework. Add paragraph about GCC's inlining. * doc/alloca.texi: Likewise. * doc/error.texi: Remove parentheses from symbol reference. * doc/gnulib-intro.texi: Likewise. * doc/gnulib.texi (alloca, alloca-opt): New nodes. * modules/fnmatch (Description): Reword to say "the ... function". * modules/full-read (Description): Likewise. * modules/full-write (Description): Likewise. * modules/safe-read (Description): Likewise. * modules/safe-write (Description): Likewise. * modules/strchrnul (Description): Likewise. * modules/trim (Description): Likewise. * modules/error (Description): Remove parentheses from symbol references. * modules/verror (Description): Likewise.
