parse_config_file: alternate comment interpretation

[xloem]

For some time parse_config_file treats all # signs as initiating comments, preventing the use of # signs in values.

It would be very helpful if a simple flag could be set, to only consider # signs in column 0, or preceded only by whitespace, as comments. This would make for clearer, cleaner code and configuration files, when configuration values contain #.

Here's an example of somebody looking for this, and being advised to write an iostreams filter to make it work:

Here's an example of brute-force key generation implemented in a production release, to make sure the key never contains the # symbol and can be stored in the configuration file:

Thanks for the suggestion. I would be open to a PR implementing such option.
