Subject: lex: add \ character into regexp for ID token
X-Git-Tag: v0.42.rc1~53

lex: add \ character into regexp for ID token

Having virtual machine up, group name contains \ character after
cgsnapshot output. lex.l does not consider this case. For example:
group machine.slice/machine-qemu\x2drhel6.4.scope {...}
Adding \ character into regexp for ID token resolves this problem.
