autofs-5.0.7 - fix master map bogus keywork match

If we have a map name in the master map that ends with a keyword
|
|
|
4d476f |
of one of the map types or "multi" we mistakenly match the trailing
|
|
|
4d476f |
white space and include that in the map name. This has to be wrong
|
|
|
4d476f |
since we can't handle quoting in the master map and embedded white
|
|
|
4d476f |
space must be escaped. It would be good if we handled quoted strings
|
|
|
4d476f |
but that has proven a bit of a nightmare so far for the current
|
|
|
4d476f |
tokenizer.
