Ok on idea, but NAK on implementation.

"A\?" to mean 0 or one "A" in BRE is GNU extention and we try to avoid it.
"A\{0,1\}" is equivalent and we already use the bound notation in "java"
section, so perhaps this is an Ok replacement?

	{ "tex", "^\\(\\\\\\(\\(sub\\)*section\\|chapter\\|part\\)\\*\\{0,1\\}{.*\\)$" },
