display them all -> allow number

[kberry]

texdoc -l bibtex says 142 results. Display them all? (y/N). That's fine, but when I previously saw the whole list, I often already know which number I want. Thus it would be nice to allow typing a number to that question, not just y/n. Just a suggestion.

Seems it's controlled by goodness of each item in the list and config max_lines (default 20).

texdoc/script/texdoclib-view.tlu

Lines 164 to 179 in f2fb792

	-- print a list of docfile objects (see texdoclib-search.tlu) as a menu
	-- if showall is false, stop as soon as a bad result is encountered
	local function print_menu(name, doclist, showall)
	local max_lines = tonumber(texdoc.config.get_value('max_lines'))
	if texdoc.config.get_value('interact_switch') and doclist[max_lines + 1] then
	-- there may be too many lines, count them
	local n = 0
	for _, doc in pairs(doclist) do
	if doc:get_quality() == 'good' or
	(showall and doc:get_quality() ~= 'killed') then
	n = n + 1
	end
	end
	if n > max_lines then
	io.write(n, ' results. Display them all? (y/N) ')

Similarly, once I wanted sth like texdoc --number 2 bibtex which will directly open the second result of texdoc -l bibtex.
