Using your code couplets (and modifying them a bit), I did some experimentation, and observed:
- the first parameter to callee, if quoted, is truncated to 8186 bytes in case the length of
the argument without quotes, exceeds the aforementioned length.
- no truncation occurs in case the parameter is not quoted.
As far as I can tell, it is not bash, but the Cygwin supervisor, that does the truncation.
