RFR: Fix number of context lines between coalesced hunks

[Erik Helin]

Hi all,

this patch fixes a smal issue with the `HunkCoalescer`. If two hunks are more than 2 * number-of-context-lines apart then we correctly calculate that they should be coalesced, but we don't include the correct number of context lines. We only include number-of-context-lines (.e.g. 5), not up to the maximum which is 2 * number-of-context-lines (e.g. 10). This small patch fixes this problem.

Thanks to @lkorinth for reporting this bug!

Thanks,
Erik
