Yes, *if* the indentation is visibly consistent.

At a previous job, I reviewed an update whose apparent meaning
differed depending on whether the editor was configured with 4- or
8-column tabstops.  I don't remember the exact details, but the code
looked like either:

    if (condition)
        statement1;
    statement2;

or:

    if (condition)
        statement1;
        statement2;

depending on the reader's settings.  Of course they're semantically
equivalent, but the first is the way the developer saw it, and the
second is misleading and is the way it looked to me.

This kind of thing is why I use only spaces for indentation and curly
braces even when there's only one statement in the block (unless I'm
working under a coding standard that says otherwise).
