snap: Only treat `---` as an info separator when it's preceded by newline (#7046)
* Only treat `---` as an info separator when it's preceded by newline
The code for splitting the output of `snap info` for multiple snaps
can't assume that `---` separates snaps any time it appears in the
output; it needs to treat that as the separator only when it's at the
start of a line. Otherwise it breaks if any snap uses `---` in its
description text, which, e.g., the `bw` snap does as of the date of
this commit.
Fixes#7045.
* Add changelog fragment
* Add a comment explaining why \n is necessary before ---
* Update changelogs/fragments/7046-snap-newline-before-separator.yml
