A ridiculously fast way of doing this is:
for i in $(pcregrep -l -M -r --include='.*[hc]xx$' \
--exclude-dir=workdir --exclude-dir=instdir '^
{3,}' .)
do
perl -0777 -i -pe 's/^
{3,}/
/gm' $i
done

Objects of this class store the SID of an item. Exchanging data with the

item is done with the virtual functions GetItemValue() and SetItemValue().
|
|
Derived classes implement these functions according to the item type they
|
|
work on.

The current tree of base classes/templates and standard item wrappers:
|

+- ValueItemWrapper< ItemT, ValueT > [1]
