Public bug reported:
In rust-sudo-rs 0.2.8-1ubuntu4 a fix was introduced that allowed for '='
to be used in commands as such:
Cmd_Alias FOO_CMD = /bin/foo --bar=1
However, this fix also made the escaped equivalence generate an "illegal
escape sequence error":
Cmd_Alias BAR_CMD = /bin/foo --bar\=1
-------------------------------------
Steps to reproduce:
1. Create a file called "test" with the following content:
Cmd_Alias FOO_CMD = /bin/foo --bar=1
Cmd_Alias BAR_CMD = /bin/foo --bar\=1
2. Run visudo on the file:
$ visudo -c -f test
3. An error is given:
test:2:36: syntax error: illegal escape sequence
Cmd_Alias BAR_CMD = /bin/foo --bar\=1
^
visudo: invalid sudoers file
-------------------------------------
What I expect to happen:
The sudoers file is parsed correctly without an error.
