`hg_prompt_filter()` does not use `get_hg_branch()` which is specifically intended to get the Mercurial branch information

This code

cmder/vendor/clink.lua

Lines 525 to 527 in 711fe28

	local pipe = io.popen("hg branch 2>&1")
	local output = pipe:read('*all')
	local rc = { pipe:close() }

does not make use of the function specifically there for the purpose of getting the Mercurial branch information, which is at

cmder/vendor/clink.lua

Lines 305 to 321 in 711fe28

	---
	-- Find out current branch
	-- @return {false|mercurial branch name}
	---
	local function get_hg_branch()
	local file = io.popen("hg branch 2>nul")
	for line in file:lines() do
	local m = line:match("(.+)$")
	if m then
	file:close()
	return m
	end
	end
	file:close()
	return false
	end

It should do that, because it is better to encapsulate details of how the branch information is obtained/formatted. For example, I use the prompt extension for Mercurial to customise the information.

Earlier versions of cmder used get_hg_branch(), and it's not clear why that was changed.
