[PATCH 0/6] local VAR="VAL"

* Update coding guidelines and test-lint script so that we quote the
  right hand side of assignment used with "local", which is buggy on
  certain versions of dash.

The first patch is not about the theme of the topic, but to document a rule enforced by the test-lint script that is not written down in the coding guidelines.

The second patch gives guidance to avoid the dash bug.

Patches [3/6], [4/6], and [5/6] are to adjust the existing tests. I think many of them are currently safe because the values they assign are $IFS safe, but some may be real workarounds for the dash bug.

The last patch introduces the test-lint pattern.

Junio C Hamano (6):
  CodingGuidelines: describe "export VAR=VAL" rule
  CodingGuidelines: quote assigned value in 'local var=$val'
  t: local VAR="VAL" (quote positional parameters)
  t: local VAR="VAL" (quote command substitution)
  t: local VAR="VAL" (quote ${magic-reference})
  t: teach lint that RHS of 'local VAR=VAL' needs to be quoted
