[GSOC][PATCH 0/2] Add builtin patterns for userdiff in JavaScript, as Microproject.

[Sergius Nyah <sergiusnyah@gmail.com>]

Firstly, I'm so sorry for the delay between selecting the Microproject and sending the patch series.
Learning about regular expressions took me a bit longer than I expected, but it was all worth it.
I'm very grateful for the opportunity to work on this project and I'm looking forward to contributing more to Git.

This patch series adds builtin patterns for JavaScript function detection in userdiff, as 
my Microproject for GSOC. The first patch adds a regular expression for detecting JavaScript
functions in Git diffs while the second adds a test for JavaScript function detection in Git diffs.
This new pattern looks for lines that start with optional whitespace, followed by 'function' and any 
characters (for function declarations), or valid JavaScript identifiers, equals sign '=', 'function'
keyword and any characters (for function expressions). It also considers functions defined inside blocks with '{...}'.
