0f48bb78a5 Remove incorrect otherwise 
You're supposed to use otherwise where you need a Boolean, not a pattern
match. This is misleadingly shadowing the real otherwise. Use _ instead.

2341a4c683 SC2256: Check for translated strings matching known variables 
SC2247 already warns about translated strings that look like $"(foo)" or
$"{foo}".  Since typical use of translated strings is to translate whole
messages, a string like $"foo" is likely to be a similar mistake if foo
is the name of an existing variable.  Conversely, a string like
$"foo bar" is potentially meant to be a message id even if foo is a
known variable.

Add a warning for the $"foo" case, but make it separate from the
existing warning so that projects that reuse variable names as their
message ids can separately disable the new warning.

84ca7711c4 Make command-specific checks act on builtin ... 
Now if shellchecks encounters a command like `builtin cmd ...`
it applies the same check that would be applied to `cmd ...`.

0e0de94045 Fix issue #1724 
(bash: missing support for 'builtin' keyword)
Now shellcheck looks for the arguments to 'builtin' to determine
read/written variables. A change in the parser makes sure that
assignments are parsed correctly in commands that start with 'builtin'.
