PATCH 1/1 docs: correct mistakes in git-merge

From: Timur Sultanaev <[email protected]>

Documentation for git-merge incorrectly notes that tip of the current branch on ascii diagram is C , while it is actually G (current branch is master, HEAD on diagram is G).

Additionally diagrams on the page are adjusted to use spaces instead of tabs, so that they align regardless of tab size. This is in line with diagrams on other git documentation pages.

To be precise, you could add to the commit message that the faulty description was introduced in 0c514d576685 (git-merge.txt: mention 'ORIG_HEAD' in the Description, 2023-01-10). (I Cc:ed Philippe Blain who authored that patch.)

This replaces tabs with spaces — though elsewhere in the file, tabs continue to roam free. The change assumes your pager or editor shares Git’s long-standing view that tabs are 8 columns wide (a convention with many loyal followers, even if not universally embraced...). That said, while correcting the description seemed fairly straight-forward, this white-space change appears to tread on more delicate territory. It might deserve its own patch — though I wouldn’t be shocked if it quietly joins the fate of the dodo.

The same applies to the white-space change at the end of this patch.

All comments are good ones for contributors to keep in mind for their next attempt.

For this particular one, which is already in 'master', there is no point in polishing and resending the patch, though ;-)

Thanks.
