Extend yat2m to allow indented tables. 

Current makeinfo versions allow to indent the texinfo source.  However
yat2m had no support for this.  With this patch it is now possible to
use a simple indentation style while keeping man pages readable.

extracted from one file, either using the --store or the --select
option.
If you want to indent tables in the source use this style:
@table foo
@item
@item
@table
@item
@end
@end
Don't change the indentation within a table and keep the same
number of white space at the start of the line. yat2m simply
detects the number of white spaces in front of an @item and remove
this number of spaces from all following lines until a new @item
is found or there are less spaces than for the last @item.
