Because shell code is inherently not like C code. That isn't my main argument, although I do think the (presumed) rationale for using spaces in C to improve usability applies here as well, even if the confines of the language don't let us go as far as in C. I'm not actually sure whether spaces inside the enclosing $(( and )) are helpful, we're much less consistent about that than about spaces around binary operators. Having looked at t/ as well now, we really do seem to favour using spaces around the binary operators so I'm further convinced this series is switching the wrong cases. > What I found particularly interesting about 180bad3 (rebase -i: respect > core.commentchar, 2013-02-11) was that it *snuck in* that coding style: it > *changed* the existing one (without rationale in the commit message, too). The last version of that patch I can find in the archive [1] doesn't add the spaces, so I think they must have been part of Junio's fixup discusses in the following messages. Although I don't think the historic context is useful in deciding which direction to go in the future.
