contrib: don't hardcode path to bash interpreter
Use the env binary to figure out the correct bash to use.
Certain systems ships with an ancient version of bash, but the
user might have installed a newer one that is earlier in $PATH.
For example the current version of Mac OS X ships version 3.2.51
of bash, which does not understand new fancy builtins such as
readarray. A user might install a newer version of bash, use that
as their shell and add that path before bin.
Simple commands:
$ echo foo
foo
$ printf 'oh no'
oh no (no-eol)
$ printf 'bar\nbaz\n' | cat
bar
baz
Multi-line command:
$ foo() {
> echo bar
> }
$ foo
bar
Return codes before inline python:
$ sh -c 'exit 1'

Doctest commands:
>>> print 'foo'
foo
$ echo interleaved
interleaved
>>> for c in 'xyz':
... print c
x
y
z
>>> print
Regular expressions:
$ echo foobarbaz
foobar.* (re)
$ echo barbazquux
.*quux.* (re)
Globs:
$ printf '* \\foobarbaz {10}\n'
\* \\fo?bar* {10} (glob)
Literal match ending in " (re)":
$ echo 'foo (re)'
foo (re)
Windows: \r\n is handled like \n and can be escaped:
#if windows
$ printf 'crlf\r\ncr\r\tcrlf\r\ncrlf\r\n'
crlf
cr\r (no-eol) (esc)
\tcrlf (esc)
crlf\r (esc)
#endif
Combining esc with other markups - and handling lines ending with \r instead of \n:
$ printf 'foo/bar\r'
fo?/bar\r (no-eol) (glob) (esc)
#if windows
$ printf 'foo\\bar\r'
foo/bar\r (no-eol) (glob) (esc)
#endif
$ printf 'foo/bar\rfoo/bar\r'
foo.bar\r \(no-eol\) (re) (esc)
foo.bar\r \(no-eol\) (re)
