6d7a7b00d7 Use ENV_USER with vars set via function -a 
ENV_USER is intended to be used when setting any variable whose name is
controlled by the user. The names given to `function -a` certainly
qualifies. This wasn't an issue in practice because the only restriction
ENV_USER imposes is also imposed on ENV_LOCAL, but the rules may change
in the future.

27dd37ebb4 Fix to indent comments in blocks properly (#1710) 
This makes two changes to parse trees:

1. Unmaterialized nodes no longer have an invalid source location
For example, with the code `while false;end` there are no tokens
associated with the while loop's job_list, and therefore it is
unmaterialized. Previously it would have had a SOURCE_OFFSET_INVALID.
But now it has a zero source length, but an offset equal to the end of
the while loop (i.e. the semicolon), and a zero length. Correspondingly,
the has_source function now checks the length instead of the offset.

2. Special (comment and error) nodes have always been "disconnected,"
meaning they are not the child of any other node. However, they now have
their parent offsets set to whatever the top of the node stack was when
the node was encountered. This gives us a sense of which node the
comment is "in", e.g. if we are constructing a job list then the
comment's parent will be the job list. This lets us determine the
comment's indent.

7dc0b6f40b Fixed various Undefined Behavior occurrences. 
Conditionally uninitialized:
 - builtin_commandline.cpp:577
 - expand.cpp:869
 - parse_util.cpp:1036

Initialization of POD structs:
 - event.cpp:61
 - autoload.cpp:22

References used with va_start:
 - common.cpp:608:18

Found with clang-3.4's awesome -Wconditional-uninitialized,
-Wmissing-field-initializers and -Wvarargs.

1fbf633817 Reimplement exec parsing. Instead of special-casing exec as a command, 
promote it to a decoration (like 'command' or 'builtin'). This makes tab
completion and syntax highlighting treat exec's first argument as a
command and is otherwise a nice simplification. Fixes #1300
