Patch to detect GLOB_NOSPACE and return better error message

sftp uses remote_glob() with ls and get, which sets GLOB_LIMIT, so it
is possible that a "get a*" command could exhaust the default limit. 
In this case you get the unhelpful error message:

sftp> get ssw*
File "/data/cora1/leka/AIA/ssw*" not found.

With the attached patch you get a better error message:

sftp> get ssw*
Too many matches for "/data/cora1/leka/AIA/ssw*".
sftp> ls ssw*
Can't ls: Too many matches for "/data/cora1/leka/AIA/ssw*"
