whitespace trimming in YIN->YANG conversion

[GoogleCodeExporter]

When doing the translation from YIN to YANG, it would be helpful to apply some 
whitespace trimming in 'description' arguments and similar strings, otherwise 
the result is ugly when theses strings are naturally indented in the YIN XML 
source. A typical result is:

  description
    "
                 Time To Live (or hop count in IPv6 terminology) that is
                 set in the IP headers of the (outer) tunnel packets. By
                 default, the tunnel packets inherit the value from the
                 inner (tunneled) packets.
                     ";


The trimming rule could be that all leading and trailing whitespace is removed 
and the second and following lines are justifed relative to the first line so 
that the above description would become

  description
    "Time To Live (or hop count in IPv6 terminology) that is
     set in the IP headers of the (outer) tunnel packets. By
     default, the tunnel packets inherit the value from the
     inner (tunneled) packets.";

Proposal: Make a new option --yang-pretty-strings, symmetrical to 
--yin-pretty-strings.

I think the pretty strings need to be handled at input time, i.e. in 
yin_parser.  So it would be better to add an option to read pretty yin strings. 
 Feel free to help out with this :)

The point is that a pretty-printed string is different for YANG and YIN, so 
when typing in YIN, the strings are indented to look reasonably as a multiline 
text of an XML element whereas in YANG the indentation is different.

My problem is that I prefer to input YIN using nxml-mode but when publishing 
such modules it is generally better to use the YANG syntax. Currently the only 
option is to reformat descriptions etc. manually.

I think this one should be closed?

A new pyang command-line option "--trim-yin" was added that does this 
whitespace trimming in the argument of 'contact', 'description', 
'error-message', 'organization', and 'reference'. Closing the issue.
