Trim whitespace from run in tasks

[joshbode]

If whitespace was trimmed (start and end of string) from the run field, then it would make it more convenient/readable to use multi-line scripts in tasks, e.g.

[tasks.test]
run = '''
printf 'args:\n'
printf '  - %s\n' "$@"
'''

which yields:

$ mise run test a b c
[test] $ printf 'args:\n'
args:
  -
sh: line 2: a: command not found
[test] ERROR task failed

note: If I put the first command on the first line, this does work but it's a bit harder to read:

[tasks.test]
run = '''printf 'args:\n'
printf '  - %s\n' "$@"'''

yielding:

$ mise run test a b 'c d'
[test] $ printf 'args:\n'
args:
  - a
  - b
  - c d

(also, only the first line of the command is shown, which is probably unnecessary)

I'm surprised this wasn't happening already

It confused me for a while because the error from sh isn't entirely helpful/obvious :)
