won't print the directory name

This commit fixes this minor inconsistency and adds corresponding test.
Closes#2254. We should only inherit global settings for keys when there
are absolutely no options attached to the key.
The default key (matching the whole line) is implicitly added only if no
keys are supplied.
Improved some error messages by including more context.
* expr: support arbitrary precision integers
Instead of i64s we now use BigInts for integer operations. This means
that no result or input can be out of range.
The representation of integer flags was changed from i64 to u8 to make
their intention clearer.
* expr: allow big numbers as arguments as well
Also adds some tests
* expr: use num-traits to check bigints for 0 and 1
* expr: remove obsolete refs
match ergonomics made these avoidable.
* formatting

Reorganize the code in `truncate.rs` into three distinct functions
representing the three modes of operation of the `truncate` program. The
three modes are
- `truncate -r RFILE FILE`, which sets the length of `FILE` to match the
length of `RFILE`,
- `truncate -r RFILE -s NUM FILE`, which sets the length of `FILE`
relative to the given `RFILE`,
- `truncate -s NUM FILE`, which sets the length of `FILE` either
absolutely or relative to its curent length.
This organization of the code makes it more concise and easier to
follow.
Create a method that computes the final target size in bytes for the
file to truncate, given the reference file size and the parameter to the
`TruncateMode`.
Add a helper function to contain the code for parsing the size and the
modifier symbol, if any. This commit also changes the `TruncateMode`
enum so that the parameter for each "mode" is stored along with the
enumeration value. This is because the parameter has a different meaning
in each mode.
Remove "read" permissions from the `OpenOptions` when opening a new file
just to truncate it. We will never read from the file, only write to
it. (Specifically, we will only call `File::set_len()`.)
