Don't loose the day of the date when editing the patent BibTeX obtained from Google

[GerHobbelt]

[EDIT]

Turns out Qiqqa cannot parse this (legal) BibTeX concatenation + string macro:

month=may # "~3"

and looses data due to the parse. (When you edit this BibTeX record in any way in Qiqqa, that month field will be damaged and only list month="may" afterwards!

Original issue text

An example (produced by enhanced DBExlorer code -- see commit 6dcc971):

BibTeX Formatted:
    @misc{graham1955audio
    ,	title	= {Audio frequency transformer}
    ,	author	= {Graham, Cecil R}
    ,	year	= {1955}
    ,	month	= {may}
    ,	publisher	= {Google Patents}
    ,	note	= {US Patent 2,707,773}
    }

BibTeX RAW FMT:
    misc(graham1955audio) - 6 fields

BibTeX Parse Diagnostics:
    
    Errors:
    
      Expecting a field name but nothing was acceptable, so moving onto next whitespace

That kind of BibTeX is NOT invalid; see the btparse manual pages here: https://metacpan.org/pod/distribution/Text-BibTeX/btparse/doc/btparse.pod

Of particular interest are the other pages referenced in the SEE ALSO section there.
