[GNC-dev] Online ID matching for OFX import

[Mike Alexander]

When I tried to do my monthly import of an OFX file containing my 
TIAA/CREF transactions it failed miserably.  I tracked it down to commit 
7853f5a2 which changed the matching of online IDs for accounts to only 
match an initial substring of the required ID.  My accounts are 
structured with a parent account in USD corresponding to a TIAA/CREF 
account and a sub-account under it for each asset in that account.  The 
online ID for the parent account is something like "TIAA-CREF.ORG 
C8304GY8 RAM001 101011".  The online ID for a sub-account storing an 
asset is created by appending the asset ID to the parent accounts online 
ID giving something like "TIAA-CREF.ORG C8304GY8 RAM001 
101011878094101".  gnc_import_select_account does a linear search of all 
accounts in no particular order looking for one where the online ID 
matches in initial substring of the ID it wants.  If it finds the parent 
account before the sub account it returns that and the process fails 
since it's the wrong currency.  I don't understand enough about the 
problem that commit is fixing to know how to fix it without breaking 
things.
