sparse-checkout: reject arguments in cone-mode that look like patterns
In sparse-checkout add/set under cone mode, the arguments passed are
supposed to be directories rather than gitignore-style patterns.
However, given the amount of effort spent in the manual discussing
patterns, it is easy for users to assume they need to pass patterns such
as
/foo/*
or
!/bar/*/
or perhaps they really do ignore the directory rule and specify a
random gitignore-style pattern like
*.c
To help catch such mistakes, throw an error if any of the positional
arguments:
* starts with any of '/!'
* contains any of '*?[]'
Inform users they can pass --skip-checks if they have a directory that
really does have such special characters in its name. (We exclude '\'
because of sparse-checkout's special handling of backslashes; see
the MINGW test in t1091.46.)
