Re: [PATCH 1/2] sideband.c: Use xmalloc() instead of variable-sized arrays.

From: Johannes Sixt <redacted>

How come we got along with this not very portable construct for so long?
Probably because the array sizes were computed from the results of
strlen() of string constants. Anyway, a follow-up patch will make the
lengths really non-constant.
