patch 9.2.0202: [security]: command injection via newline in glob()

patch 9.2.0202: [security]: command injection via newline in glob()

Problem: The glob() function on Unix-like systems does not escape
newline characters when expanding wildcards. A maliciously
crafted string containing '
' can be used as a command
separator to execute arbitrary shell commands via
mch_expand_wildcards(). This depends on the user's 'shell'
setting.
Solution: Add the newline character ('
') to the SHELL_SPECIAL
definition to ensure it is properly escaped before being
passed to the shell (pyllyukko).
