branch: master
commit 38286b6f829b37ee9044010bf927a2aaa203e3ae
Author: Vadim Zeitlin <address@hidden>
Commit: Gregory W. Chicares <address@hidden>

    Avoid vector reallocations in vector form of ledger_format()
    
    Pre-allocate all the space we need in advance, as it doesn't cost us
    anything to do it here because we know the result vector size from the
    beginning.
