1301 #  1. Characters with an ASCII value less than or equal to 32 are not allowed
1302 #  2. The character with an ASCII value of 0x7F is not allowed
1303 #  3. The characters '~', '^', ':', '\', '*', '?', and '[' are not allowed

1305 #  5. The name may not start with '.' or end with '.'
1306 #  6. The name may not end with '.lock'
1307 #  7. The name may not contain the '..' sequence
1308 #  8. The name may not contain the '@{' sequence
1309 #  9. If multiple components are used (separated by '/'), no empty '' components
1310 #
1311 # We also prohibit a trailing '.git' on any path component and futher restrict
1312 # the allowed characters to alphanumeric and [+._-] where names must start with
1313 # an alphanumeric.
