Allow customizing the bounds regex used in complete_path

[sctice]

I'm using complete-path with ctrl-x ctrl-f to find/complete a path in the link part of a Markdown link. For example, with the cursor at | in a line like [Some link](|), hit ctrl-x ctrl-f to find and complete a path.

This results in initializing the path to [Some link]() in fzf and replacing that text if a path is selected, I believe because the regex used to find the bounds of the path only considers whitespace and quote characters.

fzf-lua/lua/fzf-lua/complete.lua

Line 51 in 15d5cd9

local match = "[^%s\"']*"

I propose exposing that regex to configuration so that users can choose whatever is relevant for their application. A simpler alternative might be to add some more punctuation characters to the regex, maybe parentheses and square brackets.

Sure thing, open a feature request (or a PR if you wish to contribute) and we can add it :)
